Vertice Sales has picked up international rights on psychological thriller “Vulnerable.” Meanwhile, “Game of Werewolves,” Telespan’s first genre production, makes its market premiere at this week’s American Film Market.

Miguel Larraya’s feature debut, “After Party,” stars Luis Herdandez a teen idol TV star waking up with three girls after a wild party. Trapped in the house, they receive cell phone videos — on mobiles they can’t phone out from — portraying the real-time deaths of other partygoers in the house.

From a screenplay by Larraya and Fernando Sancristobal, “Afterparty” packs multiple plot twists, and plays with smartphone technology on and off-screen in “muscular marketing in Spain,” said Telespan 2000 founder Tomas Cimadevilla.

Telespan 2000 will produce with Telecinco Cinema.

Directed by Miguel Cruz, “Vulnerable” toplines Paula Echevarria, last seen in Spanish TV series “Gran Reserva,” as a single mother and vidcam enthusiast who returns to her family’s country estate, where she films the caretaker’s son apparently threatening her young daughter.

Now in post, “Vulnerable” is produced by Fast Forward and La Soga Films. Vertice Sales has acquired all international rights save for Germany, where the producers are negotiating a direct sale, said Vertice Sales managing director Gonzalo Sagardia.

Vertice Sales has also taken international on Xavier Berraondo’s “Paranormal Activity”-ish “Psychophony,” the remote camera record of a paranormal experiment that goes haywire.

Juan Martinez Moreno’s genre spoof “Game of Werewolves,” produced by Telespan and Vaca Films, world preemed at October’s Sitges festival.

It has pre-sold to Gulf Films for the Middle East and Visicom for Indonesia and Malaysia.

Vertice is in “very advanced” negotiations for France and Germany, and talks for sales to the U.S. and Japan, Sagardia said.

Telespan consolidated as Spain’s premier relationship comedy producer thanks to smash hits “The Other Side of the Bed,” which grossed €12.6 million ($17.9 million) at the Spanish B.O. in 2002, and “Soccer Days” in 2003, which took $17.3 million.

“We’re not abandoning comedy, but focusing more on genre. Spain is a magnificent source of new genre pic directors,” Cimadevilla said.

“Genre films function well internationally. Spanish genre is now a strong brand. We want to bet on it,” Sagardia added.
